Abstract

In this work we demonstrate a very high energy density and high temperature stability capacitor based on SrTiO3 substituted BiFeO3 thin films. An energy density of 18.6 J/cm3 at 972 kV/cm is reported. The temperature coefficient of capacitance (TCC) was below 11% from room temperature up to 200 °C. These results are of practical importance, because it puts forward a promising novel and environmentally friendly material for use in power electronics up to 200 °C and the possibility to replace supercapacitors in some high power applications.
